Implement User Sign Up

[mehalyna]

Objective: Allow new users to register (sign up) in the application.

Sub-Tasks:

1. Create User Model:

   • If not using Django’s default user model, create a custom user model tailored to the application's needs.

2. Create Sign Up API Endpoint:

   • Develop an API endpoint for user registration. This includes defining a serializer for user data and a view to handle the sign-up process.

3. Validate User Data:

   • Ensure proper validation of user data (like email format, password strength) during the sign-up process.

4. Store User Data:

   • Save the user data in the database upon successful registration.

5. Send Confirmation Email (Optional):

   • Implement a feature to send a confirmation email to verify the user’s email address.
